How Stop Loss is sent to the server (Technical Error)

Hi

With regards to the stoploss in the statement:

"ExecuteMarketOrder(TradeType, Symbol, volume, label, stopLossPips, takeProfitPips)"

Does cAlgo send the stoploss as a pip value (e.g 10) or as a price (i.e price_at_request - stoploss_pip_value).

The reason I'm asking this is I had a technical error on Executing a market order where the stop loss was not set even though a request was made. Many similar requests beforehan had been made successfully with the same volume, stop loss and take profit. I suspect the reason that an error occured this time is that the price action was moving so rapidly that the stop loss requested became invalid by the time the request was made?
